Pressure/Vacuum switches can provide an electrical signal to warn or prevent over- or under-pressurization which can be harmful to a machine or process. The pressure is adjustable.
Switches are sealed, vibration resistant, and built to provide reliable protection. They can be either direct or remotely mounted.
Switches are available in three basic conﬁgurations:
Flying leads with 18-inch (450-mm) wires.
Flying leads with female weather pack.
These pressure switches can be incorporated into a GUARDSMAN, SERIES 380, or VANGUARD modular FRL assembly. For information about such installations, contact Master Pneumatic.
